Chewing them can give you bad breath but garlic can actually be a boon for your health.Scientists have found that garlic can keep the heart healthy. Garlic boosts the body’s ability to produce allicin that relaxes blood vessels, increases  blood vessels, increases blood flow and prevents blood clots.

Scientists say that allicin reacts with red blood cells and produces hydrogen sulphide that relaxes blood vessels and keeps blood flowing. The researches also found that RBCs exposed to minute amounts of garlic juice immediately began  emitting hydrogen sulphide . Further experiments showed that the chemical reaction took place mainly on the surface of the blood cells, playing a vital role in helping cells to communicate with each other.
